How to reset vCenter 6.0 (and above) SSO password

In order to reset a lost vCenter 6+ SSO password we will firstly need to jump onto the server hosting the vCenter instance and then launch the VDC admin tool from the command prompt:

"%VMWARE_CIS_HOME%\vmdird\vdcadmintool.exe"

Hit '3' to perform a password reset and enter the SSO login (by default this is: [email protected])

It will then generate a new password you can use to login with.

Finally ensure you change password once logged in.
